Kazuhisa Uchihashi is a remarkable guitarist involved in free improvisation music. Born in 1959 in Osaka, Uchihashi began to play the guitar at age 12, playing in various rock bands, though he later studied jazz music. In 1988 he joined the band the First Edition, and in 1990 formed the band Altered States. He was also a member of Otomo Yoshihide's Ground Zero from 1994 to 1997. Uchihashi also plays daxophone, and in addition to his role as a free improviser, Uchihashi has been the musical director for the Osaka theatre group Ishinha, and has held improvisation workshops (a project known as New Music Action) in various cities in Japan, London, Oslo and Vienna.

Jon Rose is an Australian violinist born in the UK in 1951.[1] Rose began playing violin at age 7 after winning a music scholarship to King's School in Rochester. For over 35 years, Rose has been at the sharp end of new, improvised, and experimental music and media. A polymath, he is as much at home creating large environmental multi-media works as he is playing the violin on a concert stage. Central to this practice has been 'The Relative Violin' project, a unique output, rich in content, realising almost everything on, with, and about the violin and string music in general. Most celebrated is the worldwide Fence project; least known are the relative violins created specifically for and in Australia. He has appeared on over 60 albums, and worked with artists such as Kronos Quartet, Derek Bailey, Fred Frith, Shelley Hirsh, Chris Cutler, Otomo Yoshihide, KK Null, Alvin Curran, Evan Parker, Phil Minton, John Cage, Tony Oxley, Steve Beresford, Eugene Chadbourne, Bob Ostertag, Jim Denley, Elliott Sharp, George Lewis, Christian Marclay, Toshinori Kondo, Joelle Leandre, Frances-Marie Uitti, Barre Phillips and John Zorn.

Simon Rose plays baritone and alto saxophones. Born in London, England, he has performed in Europe, Canada and USA. As well as collaborating with those who play traditional instruments, Rose performs with musicians who employ self-designed instruments and electronics. He is also interested in collaborations beyond music, for example with dance. Performing solo is an ongoing project: ‘Procession,’ solo alto and ‘Schmetterling,’ solo baritone. Music recordings can be found on the labels: Emanem, Leo, PSI, Bruce’s Fingers, Not Two, Rayon and PFMentum.

Paul Stapleton is an improviser, sound artist, inventor and writer originally from Southern California, currently based in Belfast, Northern Ireland. He designs and performs with a variety of modular metallic sound sculptures, custom made electronics, found objects and electric guitars in locations ranging from experimental music clubs in Berlin to remote beaches on Vancouver Island. Since 2007, he has been lecturing at the Sonic Arts Research Centre (SARC), where he teaches and supervises MA & PhD research in performance technologies, interaction design and site-specific art. His recent album ‘FAUNA’ with saxophonist Simon Rose has received acclaim from music critics such as Ken Waxman (Jazzword), Jean-Michel Van Schouwburg (Orynx), Mark Corroto (All About Jazz), Marc Medwin (New York City Jazz Record) and others. He co-directs the Translating Improvisation research group (with Sara Ramshaw), and the QUBe music collective (with Steve Davis).
